TRACK-SAN DING DEVICE.

SPECIFICATION forming part of Letters Patent No. 486,646, dated November22, 1892.

Application filed October 3, 1892. Serial No. 447,607. (No model.)

To all whom t may concern,.-

Be it known that I, CHARLES W. SHER- BURNE,a citizen of the UnitedStates, residing accompanying drawings, sufficient to enable othersskilled in the art to make and use my invention without other inventionon their part.

The apparatus hereinafter described is a modification and improvement ofthe apparatus patented in Letters Patent No. 481,594, dated August 30,1892.

The shell of the track-sanding apparatus is of cylindrical form withends (shown in the patent, No. 481,594, referred to) and is marked inthis application K. The end of this shell is removable, as shown in theformer patent, and in the drawings at K. This end has a neck k andset-screw lo', which set-screw impinges on the shaft B, which isattached to the internal device and sets it in any desired position.

In the drawings, Figure l represents a vertical section on the line ofthe shaft B, and Fig. 2 a vertical section transverse to said line.

A A are the necks to the shell K, by which it is united to thesand-pipes, and H is a handle attached to the shaft B, by which theinternal parts of this apparatus are adjusted in position, and C2 is thehollow journal through which air is supplied to this apparatus, and C isa single air-nozzle through which the air is blown in and among thesand.

In the patent referred to the sand descended upon the top of a dome andunder the edge of the dome upon a stage perforated in the center, andthe air was applied inside of the dome.

In the present improvement on the invention the stage E, which isattached by legs G to the shaft B and to the rim F and the airpipe C2,is placed toward the induction sandpipe A or the induction sand-pipe endat the neck A instead of away from it, and the thing whichWasformerlycalled adomeD is placed farther away from the neck A, throughwhich the induction sand-pipe enters, and the part formerly called adome becomes a cup. In

other words, this apparatus may be conceived of in some degree as anapparatus in which the internal arrangements of the sandingbarrel arereversed in their relations to the necks of the sanding-barrel. Thearrangement for adjusting these parts, consisting of the shaft B, theset-screw la, and the head K', and the hollow air-pipe Ola aresubstantially like the arrangements in the patent referred to.

E is a stage on which the sand rests, and which is perforated at thecenter, as shown at E. From this stage legs G descend and connect with arim F, which has upon its interior a threaded screw, as shown. Into thisthreaded screw a cup D is screwed, which may be raised higher up, nearerthe stage E, or may be removed farther from it. With coarse sand theopening between the stage and the edge of the cup D should be Wider thanwith the fine sand, and the rim F should be sufficiently short in heightto permit the edge of the cup D to be raised considerably above theupper edge of the rim F, so as to narrow the aperture between the lowerpart of the stage and the upper part of the cup D.

Instead of having a ring with several holes in it in the dome I havefound it usually sufficient to have a single nozzle Cfor furnishing air,and the air furnished by the pipe C2 is blown through the single nozzleC into the sand column, which has descended through the stage E, andthis blast of air coming through the nozzle O carries the sand out overthe edges of the cup E before it reaches them, and down through the neckA.

It will be observed that the nozzle C is entirely above the edge of thecup D and that it delivers air into the side of an open column of sand,detaching from said open column such sand as its force may permit anddelivering it into the cavity of the cylinder, and thence carries it byforce of the blast through the neck A and into the delivery-pipe.

I do not claim in this apparatus anything which was shown or describedin the'former patent, or in another patent, No. 481,595, granted to mefor track-sanding apparatus on the same day; but I propose to derive theair for actuating this apparatus from the Westinghouse air-brake systemin the same manner as it was proposed to derive the air in the apparatuspatented August 30, 1892, No.

IOO

481,595. It' the air-blast is too strong and requires to be modified, areducing-plug C can be applied in the air-pipe C2 to prevent a waste ofair and control the sand from too Violent an action.

Having thus fully described my invention, I claim and desire to secureby Letters Patent of the United States- 1. Inalocomotive track-sandingapparatus, the combination of a hollow body having two necks, one A forattachment to the sand-pipe leading from the sand-box and the other Afor attachment to the sand-pipe leading in front of the driving-wheels,and an `interior stage E, perforated for a sand-channel and providedwith legs G, which support a rim F and having attached thereto cup D,with an air-nozzle C located between the upper edge of said cup and thelower surface of said stage, substantially as and for the purposesdescribed.

2. In a track-sanding apparatus having an interior stage E, a sandchannel through said stage, a cup covering the aperture th rough thestage of said sand-chan nel, and an air-blast between the bottom of saidstage and the upper edge ot' said cup, and the cup D, adjustable to andfrom said stage, substantially as and for the purposes described.

3. In an air-brake apparatushaving astage, a sand-channel through thestage, a cup opposite said sand-channel and extending laterally beyondthe edges of said sand-channel, and the air-nozzle C between the upperedge of said cup and the lower surface of said stage, substantially asdescribed.

4. In a track-sanding apparatus having an internal stage, a sand-channelthrough said stage, a cup below said stage and extending laterallybeyond the borders of the channel through said stage, and the air-blastpipe C2, provided with a reducing-plug C', substantially as and for thepurposes described.

5. Ina track-sanding apparatus provided with a stage E, a sand-channelthrough said stage, a series of depending legs G, and a rim F,'supportedby said legs, the combination of the adjustable cup D and nozzle C abovethe upper edge thereof, substantially as and for the purpose described.

6. In a track-sanding apparatus provided with a cup D, which isinterposed across the sand-channel and is larger in area than thesand-channel above it, the combination ot' the cup D, having aninduction sand-channel about its center and an induction sand-channelaround its edge with, an air-blast nozzle C, substantially as and forthe purposes described.
